Microsurgical treatment of ruptured intracranial aneurysm: a 120-case analysis.

Objective: to investigate the influence of pre-operative conditions and microsurgical skill on the post-operative outcomes of intracranial aneurysms by retrospective analysis of 120 cases with microsurgical treatment.
Methods: 120 patients with 134 intracranial aneurysms received microsurgical treatment via pterional approach or improved pterional approach.
Results: of 134 aneurysms, 122 were clipped, one was coated, three were isolated and there was parent artery deligation in one case. 111 Patients were cured, seven cases gave up therapy post-operation, and two died. According to GOS standard, the outcome in the discharge stage was good in 94 cases, mild disability in 12 cases, moderate disability in three cases and severe disability in two cases. Long-term follow-up was performed in all patients, of whom 95 recovered well, mild disability in 12 cases, moderate disability in two cases and severe disability in one case.
Conclusion: surgical clipping was the most effective method to treat intracranial aneurysm. Optimal chance and microsurgical technique, as well as microanatomical knowledge, are keys for successful treatment.
